I am extremely ambitious, very strong-willed, highly intelligent, and--as you may have gathered from the first third of this sentence--rarely lacking for confidence (some might even call me a touch arrogant, which is probably fair.)
I can at times come off as cold and gruff, but my friends assert that I can be quite warm, friendly, and funny once one gets past my exterior. They even try to claim that I'm nice, despite my assertions to the contrary.
I'm also rather nerdy about philosophy, science (especially soft science), science-fiction (and to a lesser extent fantasy), some video games, tabletop, and other things that only nerds can get excited about.
For those of you familiar with Myers-Briggs, I am INTJ (mildly Introverted, very strongly iNtuitive, strongly Thinking, moderately Judging.) For those of you not familiar with Myers-Briggs, I am still INTJ, but those letters likely mean little to you.
